I don't know what ips is going to  do for the next updates but privacy management really need to updated because we can't (admin or members) really managed how to deal with our informations. For instance, activity stream is very privacy killing, we can avoid to show it if we remove access to profile but profile is an important part of a forum so we can't desable something without disable something else we don't want to. etc... Please add or do something about it, privacy is surely the biggest part about what a forum is better than a social network. Thanks !

Restrict information such as your activity stream to be visible only by your friends.
